Timothy Hackworth
Timothy Hackworth (22 December 1786 – 7 July 1850) was a steam locomotive engineer who lived in Shildon, County Durham, England and was the first locomotive superintendent of the Stockton and Darlington Railway.
Youth and early work
Born in Wylam in 1786, Timothy Hackworth was the eldest son of John Hackworth who occupied the position of foreman blacksmith at Wylam Colliery until his death in 1804; the father had already acquired a considerable reputation as a mechanical worker and boiler maker. At the end of his apprenticeship in 1807 Timothy took over his father's position. Since 1804, the mine owner, Christopher Blackett had been investigating the possibilities of working the mine's short 5-mile (8.0 km) colliery tramroad by steam traction. Blackett set up a four-man working group including himself, William Hedley, the viewer; Timothy Hackworth, the new foreman smith and Jonathan Foster, a "wright". The first step in 1808 was the relaying of the Wylam tramway with cast iron plates, until then a simple timber-way. In 1811, the four-man team began investigating the adhesive properties of smooth wheels using a manually operated carriage propelled by a maximum of four men, and in the same year a single-cylinder locomotive devised by one Waters, reportedly on the Trevithick model, was built and tried for a few months with erratic results.
